Hybrid RF & FSO for Defense and 5G Backhaul

Abstract

Both defense and commercial 5G networks require ultra-broadband capacity and low latency for new applications. This paper is a collaborative development between Raytheon and NxGen Partners to develop a low cost and high bandwidth backhaul application for both defense and telecom industries. The Raytheon technology uses a Free- Space Optical (FSO) Fabry-Perot Etalon receiver that eliminates the need for adaptive optics, coupling into Single Mode (SM) fiber and synchronized local timing. The NxGen technology uses multiple Orbital Angular Momentum (OAM) modes to (i) mux and de-mux orthogonal and independent optical channels, and (ii) create isolations in an RF Full Duplex backhaul.
